FASTENI NG MEANS FOR PAPER FOLDERS AND CONTAINERS.

Application filed July 12, 1921. Serial No. 484,065.

strip provided with my improved fastening means adapting the same to beused as a wrapper or bandfor holding, sa'y,'sheets of material arrangedin layers; Fig. 2 is a perspective view of the construction shown inFig.1 with the end members turned in and in process of engaging thelocking parts; Fig. 3 is a plan view of a paper'or 2' efibre board sheethaving a form adapting it for use as a folder or container and providedwith my improved lockin means and Fig. 4 is a perspective view 0 theerected construction illustrated in Fig. 3 when in process of engagingthe locking parts.

In the form shown in Figs. 1 and 2, the construction comprises the,integrally connected body or bottom and intermediate section 1, theparallel sections 2lconnected therewith in hinged relation upon thescore lines 3 and the end sections 4 and 5 connected with the respectivesections 2 in hinged relation upon the score lines 6.

' The section 4 is provided with the transverse slot 7 havingthe-inturned or hooklike ends 7 forming the end tongues 8.

The section 5 is provided with the dovetail tongue and the reentrantloops or opencircular holes 10 intersecting the an ular section 5 andthe ends of the tongue 9. A score line 11 forms with the edges at onecorner of the tongue, a triangular car 12 edges-5 and 9. between thebody 0 the hold the parts together.

12, the corresponding tongue S engaging the v hook.

While the preferred construction involves the use of the sin le ear orhook 12, it is practicable, if it should be desired for any reason, toform an ear or hook of the other corner of the tongue 9, to cooperatewith the second tongue 8 in holding the parts to ther in assembledrelation.

11 the formshown in the constructions of Figs. 3 and 4, a paper or fibreboard sheet is provided with the body, bottom or median section 14limited by the scores 15 and 16 along which are hinged theend or sidesections 17 and 18. Flaps 19 are connected in hinged relation to thesections 17 on the score lines 20 parallel to the lines 15.

A top or end section 21 is connected in hinged relation to a section 18along the score line 22 parallel to the adjacent line 16, the part 21having a slot 23 preferably terminating in the hooked or inturned ends23 providing the tongues 24.

section 21, is hin ed to a member 18 on the score line 22 parfilel tothe adjacent line 16 andis provided with a dove-tail. tongue 26 havingthe open loops or eyes 27 intersected by the edges and 26'. A score line28 forms a triangular car 29 of one corner of the tongue 26. This ear isturned in to facilitate the entry of the tongue into the slot An endsection 25, supplementary to the 23 for eflecting the lockingengagement, the

opposite corner '30 being first entered in the slot followedcontinuously by the full entry of the tongue and the engagement of theear which sprin outward automaticallyto provide a hooked engagement. Atongue 24 engages under the=ear or hook 29 to hold the lock moresecurely in the assembled relation. While it is generally not desirableto do this, the-corner 30 may be bent back similar to the corner 29 andact in cooperation with the corresponding tongue 24 to It will beunderstood that while the unbroken corners 13 and 30 facilitate theentry of the respective dovetrations of applications of the lock orfastening means which are applicable to and intended for use withcontainers generally.

Having described my invention, I claim:

1. A folder, container, or the like comprising an integral body bent toform the ottom, sides and top of a package and having overlapping endmembers one of which is provided with a slot and the other of which isprovided with a dove-tail tongue passing through said slot and housedbeneath said slotted member, said tongue and the member of which itforms a part having edges intersected by reentrant open loops extendinginwardly from the intersection of projections of said edges, said tonguehaving a hinged corner adapted to be bent to facilitate the entry ofsaid tongue in said slot and to effect locking engagement between theoverlapping parts and form a continuous package cover.

2. A folder, container or the like having overlapping members, one ofwhich is provided with a slot having am inturned end forming a tongueand the other of which is provided with a dove-tail tongue with endsterminating in open eyes and a hinged corner adapted to be bent inwardlyfor facilitating the entry ofi said tongue second named in said slot andfor engagement with said tongue first named.

3. A folder, container or the like having overlapping members, one ofwhich is provided with a slot and the other of which is provided with adove-tail tongue having the WILLIAM R. SHRUM.
